Hi there doodee,

Unfortunately, I'm afraid you have to delete the old emails to prevent cronjob from sending it out.

As I've seen that you have a lot of emails, it will be time consuming to delete the old emails from the back-end, it will be faster if you do it from your website's database using sql query.

To do this:

1) Backup your database.

2) Access your database

3) Enter this query into your SQL delete from jos_social_mailer where id between * and **. Jos is your database name. * is the starting email and ** is the end email you wish to delete.

If you are unsure of the steps, you can give us your database access as well as the range of email that you wish to remove. We will do it for you

I hope this helps!
